1D and 2D Fourier-based approaches to numeric curvature estimation and their comparative performance assessment
A careful comparison of three numeric techniques for estimation of the curvature along spatially quantized contours is reported. Two of the considered techniques are based on the Fourier transform (operating over 1D and 2D signals) and Gaussian regularization required to attenuate the spatial quantization noise. While the 1D approach has been reported before and used in a series of applications...
متن کاملFourier Analysis and Holographic Representations of 1D and 2D Signals
In this paper, we focus on Fourier analysis and holographic transforms for signal representation. For instance, in the case of image processing, the holographic representation has the property that an arbitrary portion of the transformed image enables reconstruction of the whole image with details missing. We focus on holographic representation defined through the Fourier Transforms. Thus, We f...
متن کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولA comparative study of 1D and 2D approaches for simulating flows at right angled dividing junctions
This paper widens insight on the comparison between 1D and 2D approaches when simulating flow division at a 90 open-channel junction. For the 1D simulation, existing models regarding this issue are, on the one hand, of empirical nature and depend on the flow regime, thus not practical in the unsteady case. On the other hand, theoretical dividing models are strongly nonlinear, thus do not guaran...
متن کاملa comparative study of language learning strategies employmed by bilinguals and monolinguals with reference to attitudes and motivation
هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
